Thanks great post! Decent length, quality too! Yes, put the indicator straight up and down! It's out we can see that visually. The axles themselves are suspect the Out of Round flange in my opinion is meaningless!

 

Semi-Float all 1500's right? The lug spacing C/L off axle shaft has to be 100% the material spinning out of round is meaningless on flange. The shafts themselves are probably sub/par......you could turn down the flange if you want only to Vibe anyway probably because the Gearing is so Large now and flexing the sub/par material of the shafts and being semi-float it's creating the Vibes. The 2500's all full float and obviously more controlled.......

 

I would spend the money of Yukon and save your energy/time/money on turning down meaningless material.....

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

I do. 40-45mph and 70-77mph are the more noticeable speeds.

 

You're welcome!

 

 

I thought about that. More than likely instead of having them turned down I will just replace them with the yukon axles or aftermarket. I have vibration from 40-45mph and 70-77mph.

 

I couldn't get it to grab straight up and down. I was able to hold it in place but it was pretty much the same result. I can re-do it if need be spinning the axles by hand?? Once I seen ithe pass side wasn't that bad other than the flat spot I wasn't really concerned about getting the indicator straight up.

 

Nice video. Here's a video I took over the weekend after driving on the interstate for about 30 mins. It has now has been over 800 shake free miles since replacing both rear axles with Yukon axles. One week before I replaced the axles, I took the truck to a local shop and did a front alignment and a regular road force balance on the tires. The shake was better, but it was still there. That's when I decided to replace the axles. I did notice that the local shop used less wheel weights than what the dealership used. So I'm not sure if my truck needed less wheel weights + new axles or even if the alignment helped. Whenever the crap Goodyear SRAs wear out, I will try a regular spin balance with the new tires and I will know for sure.

More than likely I will just replace them. I have another video I took earlier slowing things down, aligning correctly etc. It's awful.

That is just amazing, never thought I would see one of these things ride that smooth. Ballpark, how much did it cost to get this axles and have them installed ?

 

 

 

And congrats, glad to see someone has one that is really fixed.

Thanks. It was right at $650 for both rear axles, seals, lug nut studs, and fluid. I installed them myself and reused the diff gasket because it's rubber. I'm assuming a 4x4 shop would charge 2-3 hours worth of labor or less.

So glad we are headed in the right direction. I love my truck minus the shake and have been here since day one. Would gladly drop $700 to make it go away.

 

I was thinking about tackling this myself as well. Where did you order the Yukon's from?

 

Thanks for your post, it gives some (if not most) of us some hope!

I ordered my Yukon gears, posi and install kit from East Coast Gear Supply, great people to deal with. I'll probably be ordering axles from them soon after hearing this. Edited by Darth_Vader

Thanks zmnypit for all of the valuable information! I'm a believer that these axles have been poorly manufactured and due to the stiffer frames, we are noticing these imperfections in the steering wheel, seats, cab and center console. I've been looking online at the runout for axel flanges and the lateral runout appears to be the key to vibrations. So far everything I read shows that the runout of roundness of the flange is negligible? RT, did you only mill down the roundness of the flange or did you also check lateral runout? Has anyone else found that information to be true. I noticed that zmnypit did do a few measurements of lateral runout. Does anyone know the actual specs? I've found that anything more that 0.004 is excessive and will cause vibration.

 

Going to be checking my axles in the very near future.

so you're looking at $1,000 to $1,250 or so to have them installed at a shop. Most shops I know charge anywhere from $84-$125/hr for shop labor. plus they will want a markup and applicable tax.

 

sound about right?

Yup... That sounds about right...

 

However, If I was still in this situation, I would offer the axle change out information to my dealer to see if they would fix under warranty...

I'd be shocked if a dealer would be willing to do warranty work with aftermarket parts. No way they would get reimbursed by GM.

They need to source better parts then. I'm tired of spending time and money trying to fix my truck that only has 22K miles.

Here's part 2. Its all the drivers side as the passenger side isnt bad. I slowed it down and took a couple angles/measurements people PM'd me about. I had to put it all back together until I get new axles then I'll swap them out and make a video if needed. Until then I'll keep enjoying my $40k massage.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.
